  • Coal Seam Gas is extracted through wells drilled into coal seams.

  • When water is pumped out, the coal seam gas is released from the coal.

  • If the pressure within the seam is high, the gas may flow to the surface unaided.

  • Conversely, the gas may have to be pumped to the surface if the pressure is lower.

  • When Coal Seam Gas comes to the surface, any water in the gas is separated and the gas is compressed and sent by pipeline to customers.
